The Gmail extension for Chrome adds a little blue icon next to your message in the message list to identify the sender.

This is a perfect tool to help you identify the sender in your inbox. The sender's domain and the official logo are added to the message in the inbox.

Gmail is one of the most popular email services in the world. It allows you to send emails and receive messages from all over the world.

You can also filter messages based on their sender to send or receive a notification to any email sent from the Gmail service.
